ABSTRACT:
A camera executes a photographing operation with multiple flashes. The camera includes a photometering unit and a control unit. The control unit controls light emission at a first electronic flash unit which is either built into or externally mounted at the camera and transmits a light signal constituting a preliminary light emission command to a second electronic flash unit provided separately from the camera by engaging the first electronic flash unit in light emission. The photometering unit photometers a subject when the second electronic flash unit executes a preliminary light emission. The control unit allows a photographing operation to be executed if a photometered value detected at the photometering unit is equal to or greater than a predetermined threshold value.
